Hi, I am using a cluster with LAM 7.1.3/MPI 2 and R 2.6.0. Rmpi version 0.5-5 is working very well. Now I have tested "Rmpi 0.5-6". During spawning the Rslaves I get an error: MPI_Error_string: error spawning process > sessionInfo() R version 2.6.0 (2007-10-03) x86_64-unknown-linux-gnu locale: LC_CTYPE=de_DE.UTF-8;LC_NUMERIC=C;LC_TIME=de_DE.UTF-8;LC_COLLATE=de_DE.UTF-8;LC_MONETARY=de_DE.UTF-8;LC_MESSAGES=de_DE.UTF-8;LC_PAPER=de_DE.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEAS...

Hi list, It appears there is a problem with the OpenMPI I/O library on CentOS 6.2 & 6.3 (package openmpi-1.5.4-1.el6.x86_64). When I compile the attached program it ends up in the error path since MPI_File_open returns 16. The corresponding (unhelpful) message is: MPI_ERR_OTHER: known error not in list I couldn't find any pointers on the net and the same program works with OpenMPI
